The rear muffler box is gone. I must say the car sounds just fabulous but how about if we just connect the pipe with no back muffler box at all! would that give the car a bit of grunt extra? and how loud will it be? is that sort of legal???
thanks every one.

welcome aboard.

Did you have any comments from the boys in blue?haha.

Ok, I think we'll go that option, how much in average does it cost?Australia Best said they can replace the rear one(s) for $280. But It was too quiet when the muffler were ok. We lowered the car so bad I know the back muffler will be destroyed soon anyways.

I was just considering just the original pipe only! I like the original double exhaust it tells the Holden boys they've been smoked by a stock XR8:) love it. I don't want them to think it mus be supercharged.She's a stock beaty made by Tickford:s6:

AU MUFFLER

THE WHOLE JOB COST ME ABOUT $500 . AND THE BOYS IN BLUE HAVE NOT GOT HOLD OF ME YET. THE ONLY DOWNSIDE OF THIS SYSTEM FOR ME THAT IS IT IS A LITTLE BIT CRACKLY ON OVER RUN(BACKFIRES) BUT STILL TURNS HEADS ESPECIALLY THOSE HOLDEN BOYS IN THEIR SICK SOUNDING CHEVS THAT SOUND LIKE SOME SORT OF KITCHEN APPLIANCE..

The XR8's sound a lot better than the Gen 3 Chev V8 with a system on them. However, a dual 2-1/2" is too big for the Ford and it loses off the mark power. We ended up putting an "X" pipe in one to give it some backpressure and it picked up a heap of power and torque while retaining the awesome sound.
